THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 368,282, dated August16, 1887.

Application filed April 18, 1887. Serial No. 235,277. (No model.)

To all whom it may concern:

Be it known that I, DENIS M. DENEHY, a citizen of the United States,residing at Acamp0, in the county of San Joaquin, State of California,have invented certain new and useful Improvements in Thin-Couplings, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

My invention relates to an improvement in appliances for attaching theshafts of a vehicle to the fore axle; and it consists in the combinationand arrangement of certain parts, as hereinafter explained, and pointedout in the claim.

Referring to the accompanying drawings, Figure 1 is an elevation of athillcoupling and section of a shaft, showing my invention. Fig. 2 is asection of the same.

A is the jack-coupling, suitably attached by its clips to the axle andprovided with forks for the reception of the thill-head B, which issecured in the fork by the shackle-bolt a. The head B is constructedwith a recess beneath, into which is inserted a slide-block, 0,completing the head B, which also is provided with a projecting arm, I),which receives a lock-nut set-screw, 0, having alock-nut, c, thereon,the foot of which is slightly countersunk into the slide-block O.

\Vhen it is desired to detach the thills from the vehicle, the-set-serewO is run back, permitting the removal of the block 0', after which thehead B and its attached shaft may be lifted away from the shackle-bolt aof the jack-coup ling A. To attach the shaft, the head B is placed inposition upon the shackle-bolt a. The block 0 is placed in its positionand the lock set-screw is screwed up tightly thereon. This method ofattaching and detaching the shafts is very simple and expeditious.Rattling is likewise prevented by keeping the bloek G in close contactwith the shackle nut a by means of the set-screw O and lock-nut c. Thesliding or adjustable block 0 forms a part of the tliill-head B, andwhen inserted in such head fits snugly, thereby not permitting any dirtto get in upon the wearing-surface of the eye and bolt, as is the casewhere an extra friction-plate is used.

Having thus described my invention, what I claim is- In athilbcou'pling,the combination, with the shackle, of the thill-iron having the angularbranch tapped as shown, the screw passing through the said tappedbranch, the bearing for the shackle-bolt, and the nut on the screwoutside of the said angular arm, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
